That is interesting and useful information. I just don't like the window's functionality of clicking the window and getting a target. Different click lengths get different results.
I guess you could disable the functionality of the input, and then manually get the target and cast using useability? I dunno the difference in the game system and if it will not target quick enough. Or since it's just the player window, you could clear target.
My main concern was just getting abilities to queue, and not change target.
For things like a specific encounter, and needing to cure yourself because game-functionality is altered, can really be solved with a hotkey casted spell.
And when it's dealing with yourself, keyboard is usually faster than mouse anyhow. But otherwise, it's all just opinion based stuff
